SHEET RECEIVING AND FEEDING MECHANISM.

Applicatibn filed January 12, 1923. Serial' 1%. 612,321.

To all whom, it may concern:

Be it known that I, ALBERT BROADMEYER, a citizen of the United States,residing at Harrisburg, in the county ofiDauphin and 1 State ofPennsylvania, have invented certain new and useful Improvements in SheetReceiving and Feeding Mechanisms, of which the following is aspecification.

While the present invention is peculiarly useful in connection withruling machines of; the type known as Dual-L, in which the sheets afterbeing ruled in one direction by one apparatus, are fed to another rulingapparatus arranged at right angles thereto for ruling lines transverselyto the first lines ruled, there are features of the invention that areuseful in connection with trating the sheet-receiving other types ofmachines. I a

The object is to provide means for receiving sheets moving in apredetermined direction and startin said sheets in an angular direction,sai means being simple and practical and capable of being'proper lytimed, so that each sheet will be removed from the path of thesucceeding sheet and there will be 'no interference or piling up betweensuch sheets.

In the accompanying drawings V Figure 1 is a plan view of the abovedescribed type of ruling machine, and illusand delivering means, I y

Figure 2 is a longitudinal sectional View taken substantially on theline 2-2 of Figure 1 Figure 3 is a sectional view on the line 33 ofFigure 2,

Figure 4 is a plan view of and delivering means.

Figures 5 and 6 are detail sectional views, respectively, on the lines55 and 66 of Figure .4. p

In the accompanying drawings,the first of the two ruling machines isdesignated generally by the reference numeral 7, and the second machineby the reference numeral 8. These two machines may be of any well knownor desired character, and are shown diagrammatically. The sheets thereceiving is so placed that the ends, said brackets being slidable onguide bars 13. The adjustment of the stop plate 11 along the supportingbars 10 is effected by sprocket chains or cable members 14 that passaround sprocket wheels 15 located below the end portions of thesupporting bars 10, said sprocket chains being connected to the brackets12. By moving these chains, obviously the plate 11 can be moved todifferent positions. For the purpose of effecting the movement of thesheets along the supporting bars 10, endless tapes 16.. are employedthat pass around rollers 17 at the ends of the bars. The rollers 17 atthe rear end of the machineare carried by a shaft 18 that is belted, asillustrated at 19 to one of the rollers 20, around which the conveyingbelt and cords of the machine operate. f

Located in the rear end of the machine 7 alongside the supporting bars10 and adjacent to the juncture of the machine 8 with the machine 7, isa sheet-moving member in the form of a roller 21 that is disposedlongitudinally of the direction of movement of the sheets over the bars10. This roller 21 is continuously driven from the second machine 8through suitable gearing and beltin illustrated generally at 22 inFigure 1. t margins of the sheets delivered on to the supporting rods 10will overlie said roller, as indicated at A in Figures 3 and 6. Arrangedlongitudinally above the roller 21 is a shaft 23 that is pro-1 videdwith one or more gripping cams 24. The perip eral portion of each camfrom B to C, as shown in Figure 6, is on the radius of a circle thatwill cause said portion to coact with the roller 21 and grip the marginof the sheet A againstthe same.

The rcfrom the roller 21.

maining portion of the cam is of considerably less diameter, and asindicated in Figure 6, is thus spaced a considerable distance The'shaft23 furthermore carries at one end a friction wheel 25, the radius ofwhich is such that it will also coact directly with the roller 21, butwhich has a cut-out portion 26 that leaves a space between said roller21 and wheel 25 when the cams 24 are out of coaction with the roller 21.This will be clear by a comparison of Figures 5 and 6. The shaft 23 isfree to rotate and it is overbalance'd by the utilization of weights 27and 28 carried by the cams 24 and friction wheel 25. Said shaft is,however, normally held against movement, and 'to'this end it is providedwith a pin 29 adapted to be engaged by one arm 30 of a, stop leverpivoted on the frame of the machine 7, as shown at 31,.and having itsother end 32 coacting with a cam 33. This cam 33 is mounted on a shaft34 journaled transversely in the frame of the machine 7,

and geared as shown at 35,ein Figure 1, to

delivered on to the rods 10, as will be evident. Each is carried alongthe rods 10 by the tapes 16'until stopped by the plate 11. During thismovement, although the roller 21 is in operation, the shaft 23 isstationary with the cams 24 raised. Thecontrolling cam 33 for the stoplever 30-32 is continuously in operation and is timed so that when asheet is positioned against the stop 11, the stop arm 30 is raised. Thismovement is occasioned by the arm 32 riding against the flat portion ofthe cam 33 and a spring 32 serves to swing the lever and raise the arm30 out of engagement with the pin 29. As soon as this takes place theshaft 23 is released and the weights 27 and 28 will cause an initialrotation of the shaft and of the friction wheel 25 and cams 24. Almostimmediately the periphery of the friction wheel will engage the roller21 and continue the rotation of said shaft. As this movement takes placethe cams 24 will move into coaction with the roller 21, thereby grippingthe paper sheet A thereagainst and starting its movement at right anglesand into feed ing engagement with the rollers 37 38' and 39. The shaft23 makes one complete rotation. By that time the stop arm 30 has beenagain depressed into the path of the pin 29 and the gripping cams againbecome inactive. By this time, however, the sheet has been seized by thefeeding mechanism of the second machine 8, and is carried off thereby.This 0 eration takesplace periodically as succeedi sheets are delivered.

From t 1e foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size. shape, proportion and minordetails of con struction may be resorted to without departmg from thespirit or sacrificing any of the advantages of the invention.
